PROBLEM TO BE SOLVED: To prevent a game value from being excessively provided, in a slot machine that can generate a variable probability state.SOLUTION: A slot machine includes: a special game generation means (game controller 50) for generating a special game state winning a normal prize symbol combination winning at a probability higher than that in a normal game state, on the basis of the formation of winning a special prize symbol combination winning; and a variable probability means (the game controller 50) for generating the variable probability state winning the special prize symbol combination winning at a probability higher than that in the normal game state, on the basis of formation of prescribed conditions. The result of an internal lottery includes: a normal winning in which the normal prize symbol combination winning is won; a special winning in which the special prize symbol combination winning is won; and a duplicate winning in which the normal prize symbol combination winning and the special prize symbol combination winning are won in duplication. An internal lottery means (the game controller 50), in the variable probability state, makes the winning probability of the special winning higher than that in the normal game state, with the winning probability of the duplicate winning maintained at the same probability as the normal game state. |
